What have I gotten myself into?

Very ambitious project. Fun to watch. Thanks for the entertainment :)

Can you see any reason I could not do a similar rear stance on a 69 Dart without the 4 link? I'd like to put the frame 3 to 4 inches off the axle with the widest feasible tire and 18 - 20" wheel.

I'm thinking I may try autocross. I imagine I should leave a little extra room for lateral movement of the diff.
